X-Pro1 Frozen

I had a similar issue. It occurs when you shoot in continuous mode or bracketing where the camera will batch these shots together. Say that you shot three shots. Deleting two works fine, but the last one remaining in the batch, it gets confused. Not sure if it actually freezes, a few times I thought it did. But when I pushed the display button, it hops out of the "batch mode" and I could delete the pic and continue as usual.
